37 to 40 GHz Power Amplifier with Power Detector

Hittite Microwave Corp. has developed a new power amplifier that is ideal for high linearity point-to-point and point-to-multi-point radios and VSAT and SATCOM applications. The HMC7229LS6 is a four-stage GaAs PHEMT MMIC power amplifier with an integrated temperature compensated on-chip power detector that operates between 37 and 40 GHz. Ideal for covering the 38 GHz licensed microwave radio band, the amplifier provides 24 dB of gain and +31.5 P1dBm of output power while drawing 1200 mA from a +6 V DC supply.

With an OIP3 of +40 dBm, the HMC7229LS6 is also ideal for linear applications such as high capacity point-to-point or multi-point radios or VSAT and SATCOM applications demanding +32 dBm of efficient saturated output power. The RF I/Os are internally matched and DC blocked for ease of integration into higher level assemblies. The HMC7229LS6 is housed in a ceramic 6 × 6 mm high frequency air cavity package that exhibits low thermal resistance and is compatible with surface mount manufacturing techniques.

The HMC7229LS6 complements Hittite’s extensive line of power amplifiers that provide frequency coverage for all of the licensed microwave radio bands from 6 to 86 GHz. Samples are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.
